' FLEHBLE conferme.

Be it'known that 1,-R0BERT LEE Lower, a citizenk of the United States,residing at Louisville, in the county of'Jefferson and State ofKentucky, have invented certain new and useful Improvements invFlexible' Couplings; and l do declare the following -to be a ful clear,and exact description-of the invention, such as will enable othersskilled I in the art to which it appertains to make and I necting strapsor links 7 is use the same, reference i being had to theaccompanyingvdrawings, and to the letters and figures Iof referencemarked thereon, which form a part of this specification.

` Fig. '2 is'a side elevation looking` endwise on consists in the novelMy invention relates to flexlble couplings, and has for its-object toprovide a. device of this class whereby two shafts an'fbe coupledtogether even though they be slightly out of alinement, or one be at aslight angle tothe other. f

With these objects in view my invention construction andarrangementofthe flexible connecting straps or links, and my invention also consistsin the. combinationof the straps or links with the coupling members allof which will be first fully described and afterwards specificallypointed out in the appended claims. l

v Referring to the accompanying drawing: Figure 1 is a sideelevation ofthe coupling.

to theconnecting straps or links, and, Fig. 3 is a plan iew of thecoupling, the upper coupling member being shown ,transparent in order toillustrate the location and arl rangement of the coupling 'straps orlinks.

Like numerals of yreference indicate the same parts throughout theseveral figures, in which,

1 indicates the coupling comprising two ,coupling members 2 and 3,andfor convenience the coupling member 2 will be termed the drivingmember and coupling member 3 l the driven member, 'which coupling membercomprises preferably a disk 4 having a sleeve or collar 5 land a centralopening 6 to receive the shaft. -v

7 and 8 indicate the 'IieXible-connecting straps or links which may `beconstructed of l, any suitable flexible material such as leather, lIcanvas, rubber, cable, etc. As -shown mi Fig. 3 the connecting straps 7are longer than A Specicatonof Letters Patent. applicati@ mea January1s, 1907. serial No. 352,899.

the straps 8 andare disposed on the cou ling members 4intermediate thestraps 8 and c oser to the center of the coupling members all of saidstraps or vlinks being arranged at substantially right angles to theaxis of the coupling members as shown in Figs. 1 and 3.

Considering the disk'4, shown in Fig. 3 as being the lower or drivenmember 3, it will be seen that the lower end 9 bolted to the disk 4 bymeans of a bolt 10 andnut 11 while the ppper end 12 of the otherconnecting strap or 7 is also secured to the disk 4 by means of a bolt10 and nut 11.

Referring now to the shorter connecting straps or links 8 it will'beseenthat the upper end 13 is secured to the disk 4 by means ofa bolt 1()andnut 11; while the lower end 14 of the other short strap or link 8 issecured to the disk 4 by means of a bolt 10 and nut 11; whilethe upperends 15 and 16 of one of the long links 7 and shortlinks 8 are bolted tothe upper er driving member 2 by means of bolts'1-7, while the ower ends18 and 19 of one of the short straps 8 and long straps 7 are bolted tothe upper or driving member 2 by means'of bolts 17. The effect of thisconstruction is that all of the connecting straps instead of being atright angles to each other .or angularly disposed to each other, areparallel, and each pair of or links on both sldes of the disks are toeach other, as illustrated in Fig. 1.

Having thus rfully described `the several arts of my invention itsoperation as folows: The coupling members 2 and 3 being secured to theirshafts the longer links 7 are lbrought into operation when the drivenmember 3 is being rotated in the direction of paral of one of the conLoUisvILLn, KENTUCKY, AA ssrenon orfo'Ns-HALF 'ro-.HARRY B'.

connecting straps el thearrow in Fig. 1; while the shorter links 8 arebrought into operation when the driven member 3 is being rotated in thedirection opposite tothe arrow.

Having thus fullydescribed the several parts of my invention, what Iclaim as new and desire to secure by Letters United States, is,

A flexible coupling comprising a driving member, a driven member, aseries of flexible links or straps connecting said members, said linksor Astraps being arranged in pairs, the outer strap or link of each pairhaving one Patent of the emi seemed im 'me driving member and its ntesimony whereof, I ax my signature, m presence of two wltnesses.
